How to Build a Rotating Media Cabinet

Cut 7 squares from the plywood, each 24 inches by 24 inches. These will become the base, bottom, top, and 4 shelves of your cabinet. Measure and cut each shelf into four quarters.

Cut one wide divider and two narrow dividers for the sides of the cabinet shelves. Cut a 54-by-24 inch sheet of plywood for the wide divider, and two 54-by-12 inch sheets of plywood for the narrow dividers.

Attach the shelves to the narrow dividers. Lay each narrow divider on its edge. Clamp to a work surface to hold them steady. Measure and mark the placement of each quarter-shelf along both flat sides of each narrow divider, spacing about 10 inches apart. Align the shelves against these marks and screw in place with 2-inch screws.

Attach the narrow dividers along the flat sides of the wide divider. This should result in a four-sided cabinet. Secure in place with 2-inch screws.

Center the shelf assembly over the rectangular bottom piece of the cabinet. Screw in place to the dividers.

Assemble the lazy Susan wheel. Center the circular 12-inch lazy Susan onto the rectangular base piece. Align the screw holes on the rings and mark the access hole on the lazy Susan by driving a nail into the plywood and removing it. Remove the lazy Susan and drill a 3/4-inch hole over the mark in the plywood. Replace the lazy Susan, align the access hole with the hole in the plywood, and attach the ring to the base with 3/4-inch flathead screws.

Attach the base to the shelf assembly. Align the base with the bottom of the shelving. Align a screw hole in the top ring of the lazy Susan with the access hole. Attach the top ring to the bottom of the shelf assembly by drilling a 3/4-inch flat-head screw through the access hole. Rotate the bottom piece to align the remaining screw holes in the lazy Susan ring with the access hole. Attach with additional screws.

Attach the 3-inch rectangular lazy Susan to the top of the shelf assembly. Screw the bottom ring of the 3-inch lazy Susan to the dividers at the top of the shelf assembly with 3/4-inch screws. Align each corner of the lazy Susan with each of the four divider pieces extending from the center of the shelf assembly. Attach the top piece of the shelf assembly to the top ring of the lazy Susan.

Build the four doors of the cabinet. Assemble the doors one at a time. For each door, use the lumber to construct a rectangular frame to span the width and height of one side of the cabinet. Secure the frame with 2-inch screws. Measure and cut a pane of acrylic to fit on the back side of the door, and mount the acrylic on the back of the frame. Secure with carpenter's glue.

Attach the doors to each side of the cabinet. Make sure each door will open in the same direction. Attach to the cabinet with metal hinges and screws. Use one hinge for each shelf. Attach a doorknob to the front of the door with epoxy. Make sure all knobs are on the same side for each door.
